(54) Macroreticular carbonaceous material useful in energy storing devices


(57) The present invention relates to an energy storage device comprising a macroreticular carbonaceous material having a distribution of micropores, mesopores and macropores wherein the macroreticular carbonaceous material has a total surface area of from greater than 500 m2/g to 2500 m2/g and wherein 20% to 80% of the total surface area is due to pores with diameters of from 17 angstroms to 100,000 angstroms. In addition, the present invention relates to an energy storage device comprising a macroreticular carbonaceous material having at least one first distinct peak representing a pore size of less than or equal to 20 angstroms when measured utilizing H-K dv/dlog(W) pore size distribution and at least one second distinct peak representing a pore size greater than 20 angstroms when measured utilizing BJH dv/dlog(D) pore size distribution.
